- 8 Claims.

My invention relates to containers, and more particularly to containers of the portable type, formed from blanks of creasable material.

In the matter of dispensing and merchandising commodities, and more particularly commodities of a perishable nature, such as oranges, apples, cantaloups and the like, such commodities are either shipped in bulk or packed in boxes or crates holding considerably more than the average consumer purchases at one time. When the commodity finally reaches the store or market, for sale to the consumer, it more often than not, is displayed in bulk in an open basket or stand, or left in an open crate to be picked over by a customer in making a selection. Between the time of shipping and the ultimate transfer to the consumer, the commodity has been exposed to much handling and abuse which is conducive to an increase in the percentage of spoila a d loss, and the proprietor is left with a poor grade of product aft-er the first few customers have made their selection of the choice items.

Among the objects of my invention are:

1. To provide improved merchandising means, preferably for perishable commodities, such as fruit or the like, which shall cut down the amount of handling and abuse to which such commodities are customarily exposed between the time they are shipped and the time they pass into the hands of the ultimate consumer.

perishable nature, which will conveniently enable the arrangement oi' the choicest items in a manner best adapted for merchandising and display purposes.

7. To provide an improved container for the packaging of commodities, preferably those of a perishable nature, which shall assure maximum protection to the contents thereof.

'8. To provide an improved container for the packaging of commodities, preferably those of a perishable nature, which shall retain its utility,

' following removal of the contents thereof, and.

2. To provide means for the packaging and shipping of commodities, preferably commodities of a perishable nature, in measured amounts commensurable with the purchases of the corn sumer, whereby the commodity reaches the consumer in its originally Packed condition, undisturbed by any intermediate handling.

3. To provide an improved container for the packaging of commodities, preferably of a perishable nature, which container shall be inexpensive, compared to the cost of the commodity to be packed therein, to justify the dispensing of such container with its contents.

4. To provide an improved container for the packaging of commodities, preferably those of a perishable nature, which shall be su'fliciently resistant to collapsing pressures as to permit stacking of the same for shipment,without injury to the contents thereof.

5. To provide an improved container for the packaging of commodities, preferably those of a perishable nature, which shall quate ventilation of the contents.

6. To provide an improved container for the packaging of commodities, preferably those of a which shall be of sufllciently rugged construction as to lend itself to a variety 01 uses.

Additional objects of my invention will be brought out in the following description of the same taken in conjunction with the accompanyme drawings wherein-- Figure l embraces plan views of the blanks from which one ement of my improved container is assembled,

In general, my invention-contemplates the provision of a shipping and merchandising container adapted to be packed with commodities, preferably those of a perishable nature,"such as fruit, and capable of protecting its contents throughout designated as blank such shipment and handling as is necessary to bring the contents into the hands of the ultimate consumer. To-this end, the container is fabricated from assembled blanks, and, in its finished form, embodies many features rendering it a highly desirable container for such purpose. The same is provided with ventilating openings in the form of open corners, enabling the contents of the container to be exposed to ventilation at all times. The w. .lls of the container have cushioib ing characteristics, enabling the contents to be pressure packed and maintained in this condition throughout shipment and handling, in spite of such shrinkage as may take place in the commodity.

The wall structure which imparts thereto its -aforementioned cushioning characteristics, at the same time serves to brace the walls and render the container highly resistant to collapsing pressures, thus enabling the packed containers to be stacked for shipment, without danger of injuring the contents thereof. A carrying handle, is formed integrally from the material of the container, but during shipment, is adapted to lie within the plane of that portion of the container from which it is formed, and thereby not interfere with the stacking ability of the containers during shipment.

At an intermediate stage in the assembling of the container, the container the blanks to form assembly provides an open-sided frame which includes the top wall, bottom wall and end walls of the container. The sidewalls of the container are hingedly secured at opposite sides of the container. One of these hinged sides, come the cover. is-p'refe'rably removably sealed to close one side of the frame, and in packing the container, this closed si e temporarily functions as a bottom against whichchoice items may be arranged in any desired and attractive pattern, after which the packing of the container is completed and the otherjside Wallis then permanently secured in closedpo-sition. Thus, when the cover is subsequently opened, the neatly arranged choice items will be the first to be' exposed to view. Where pattern packing is not desired, the container. at this intermediate stage of its manufacture, lends itself very effectively to loading with a commodity by dump delivery on fast assembly lines. l 1

For a more detailed description of my invention, reference will be made-to. the accompanying drawings. I

One embodiment'oi' the complete container is assembled from three blanks. Two of these blanks are identical,:and for convenience of description and future reference, one of these blanks will be designated as blank 'A,; while' the other will be B. Blank A only need be described, whilecorresponding parts of blank B will be designated by primed reference numerals. Blank A, accordingly, includes a substantially rectangular panel I having rounded off corners 3 joining the two short. sides 5 with the two long sides 1 thereof. The two'short sides are marked ofl on the blank by double, closely spaced score lines 9, while the; longer sides'of the panel arealso determined by score lines, though one of the longer sides is marked off by a single score line I I, while the other is marked oil by a pair of closely spaced score lines l3. At each end of the substantially rectangular panel I, along the short sides marked ofi by the double score lines 9, there extends a relatively narrow tab l5. Along that longer side of the panel marked off by a double which is to be- 1 a common boundary. boundary, the panel 2! is bounded on each side score line N, there also extends a relatively narrow tab I'I having a single score line 18 marked of! thereon, parallel to the double score line l3. Beyond this single score line, the tab tapers to its free edge. Along that side opposite the tapered tab l1, an approximately square panel 2| joins the first panel, the single score line H forming Normal to this common by a pair of double, closely spaced score lines 23. This substantially square panel terminates opposite the first panel in a free edge 25. Extending from each of the sides of the pane1 2|, determined by the double score line 23. there extends a tab 21, terminating in a free edge 29 substantially in alignment with the free edge of the end tabs l5 of the first panel I. Each of these tabs has a corner beveled at that end adjacent the free edge of the panel 2|, while the edge 29 of each of these tabs is scalloped or otherwise disfigured to provide an irregular contour.

The third and remaining blank, which for convenience will be referred to as blank C, comprises two end sections 3| joined together by an intermediate section 33. This intermediate section includes a substantially rectangular mid-portion having rounded corners 31. It is provided with parallel score lines 39 equally d from the longitudinal axis thereof, these 3: re lines extending inwardly a short distance from the ends of the mid-portion. Beginning at the end 'of each of such score lines, the mid-portion is die out along a curve 4|, which in its initial portion turns in the general direction of a neighboring comer 31 of the mid-portion, and then reverses in a direction to follow the general curvature of such corner, terminating at a point 43 spaced from that side of the mid-portion, toward which the particular curve led. The terminating ends 43 of such die cuts on each side of the longitudin'al axis of the mid-portion, are joined by a score line 45 parallel to such axis, and the area bounded by such Joined die cuts is severed by a die cut 41 extending between the curves at an intermediate point thereon and parallel to the longitudinal axis of the mid-portion.

The intermediate section of the blank C, in addition to the rectangular mid-portion 35, includes a pairof substantially semi-circular sections 43, each integrally extending from one end of the longitudinal area of the rectangular midportion 35 lying between the parallel score lines 33. Each semi-circular section 49 terminates at a score line 5| in the blank C, from which extends an end section 3 I, each end section including a rectangular panel 53 extending longitudinally from the score line 5i and terminating in a free edge 55. The longer sides of each rectangular panelare marked off by double score lines 51, and from these longer sides, extend tabs 53 which are reduced by a slightly stepped taper ii, to a longitudinal dimension slightly less than the length of the panel side to which it is joined. Like the tabs of the blanks A and B, the free edges of these tabs are similarly scalloped.

The dimensions of the blank C with respect to those of blanks A and B, are such that the length of the intermediate section 33 is equal in length to the longitudinal axis of the rectangular panel I, and the width of the rectangular end panels 53 of the blank C is substantially comparable to the length of the short sides 5 of the rectangular panel I of blanks A and B. The length of each of the rectangular end panels 53 of blank C is made the same as the length of the substantially square panel II of blanks A and B,

as measured normal to the common boundary score line H.

In assembling the above described blanks to 'form the improved container of my invention, the tabs 21 of blank A are folded inwardly and stapled to the panel 2i with which they are associated, at points close to the score line Ii, thus to form a side wall 84 of the container when completed. The blank is then creased along this score line H, thereby placing the panel i in position to function as part of the top wall structure of the container when finished. The tabs II extending from theends of this panel, are bent over at substantially right angles to the plane of the panel. The blank is now positioned longitudinally upon this .top wall rectangular panel, and stapled thereto at spaced points,

preferably between the score lines 39 on the midportion- 85 of the intermediate section 33. The end sections 3| are then bent over the end edges of this panel I, along the score lines II Joining the endpanels to the semi-circular sections 48, to complete the top wall of the container. With the end panels in this bent-over position, the end panel tabs 58 are folded inwardly about the depending tabs ill of the rectangular panel i, and stapled thereto. Each end of the rectangular panel I during this assembling operation is clampedbetween an end of the intermediate section 33 and the adjacent ends of a pair of tabs 59. The stepped taper in this end of the tab facilitates the folding of these and panel tabs about the rectangular panel tabs it, while providing for the clamping effect noted, which in the finished container, serves to provide added support for the top wall corners of the container.

The blank B is creased and stapled in a man-7,.

ner similar to that of blank A, prior to its assembly with the blank C. Thus, blank B will have each of its tabs 21' turned in and stapled against its associated panel 2|, at a point close to the scoreline II, to form another side wall of the container when completed; and the blank will be creased along the score line Ii to place the rectangular panel I' in position to form the bottom wall 69 of the completed container. The tabs i5 extending from the short sides of this rectangular panel I, are bent at right angles, similarly to the bending of the corresponding tabs of the blank A, The blank B, thus creased and stapled, is assembled to previously assembled blanks A and C, by inserting the tabs l5 underneath the inwardly folded end wall tabs 59 until the bottom wall panel I bears against the stepped taper iii of the end wall tabs 59, at which time the end wall tabs 59 and the inserted tabs I 5' are stapled together, thereby completing the end walls H for the container. The tabs 69 thus gauge the spacing between the top and bottom walls during assembly and assure uniformity of height in the finished container. m

At this stage of the assembly, the container presents an open-sided frame, including the top wall 65, bottom wall 69, and end walls II, with the end walls narrower than the width of the container. A side wall 64 formed by the panel 2| of the blank A with its inwardly directed stapled tabs 21, will be hingedly secured to the top wall 65, and will have a length less than that of the top wall 65. This side wall 64 is adapted to substantially close one of the open sides of the frame. The opposite side wall 64' formed by the rectangular panel 2i of the blank 13 and its associated inwardly directed stapled tabs 21' will be of similar size to that of'the first side wall, but hingedly secured to the bottom wall, and in its closed position, will be adapted to subst'antially close the other open side of the frame.

From the viewpoint of merchandising, this construction lends itself very admirably to the packing of the container. To this end, the upper wall tab I1 is tucked in under theside wall tabs 21', and the side wall 64' is removably sealed in its closed position, to the top wall 65, by a removable piece of adhesive 13 or the like. The insertion of the tab I1 is facilitated by'th'e combination of the double score line i3 and the single score line It formed in the blank, since the double score line i3 defines a line of greater weakness to bending than the single score line i9, whereby in the act of inserting the tab, the crease will occur along the double score line, in preference to the single score line. score line I 9 will accordingly; in the operation of inserting the tab, enablea sufficient arcing of thetab .to facilitate its insertion, without creasing. This possesses the advantage of maintaining stiffness in the tab material, whereby the frictional holding power of the tab, in its This removably sealed side wall 64' functions as the cover of the finished container, and while in its temporarily sealed condition," the container may be conveniently packed, through the remaining pen side, with the cover temporarily serving as the bottom. In this position, the container presents a large opening fthroughwhi'ch to fill the same, thereby readily lending itself to dump loading on high speed conveyors. Where hand packing is desired, choice items maybe neatly arranged and patterned against the cover, to present the desired display eifect when the cover is subsequently opened by a purchaser. Following the complete fillin of the container with the desired commodity, the other side wall 64 is permanently closed, byinserting the bottom wall tab. ll under the side wall tabs 21, and stapling the same together. g

The container thus assembled, while of general utility, incorporates many features, some of which are of particular advantage in the merchandising of perishable commodities, such-as fruit and the like. An important feature of this container, from this viewpoint, is the presence of open corners which provide for cross ventilation of the contents therein, a feature which permits cold or humid air to 'reach all parts of the pack quickly, and thus reducing the time required for pre-cooling in preparation for shipment. The open corners at the same time provide 'sufilcient exposure of the contents for inspection by the prospective purchaser, todetermine quality and condition thereof.

The tabs 21 and 21, and 59 in the finished container, during the operation of stapling the same to their respective walls at widely spaced points, as described, tend to bulge away from their [associated walls, intermediate the points ofstapling, thus causing the greater pcrtionof such tabs to be in spaced relationshiptov such walls and at an acute angle with respect thereto. This is particularly, true, if the container is of relatively stifl', resilient material, for-thetabs become resiliently hinged when turned inwardly out" of the plane of their respective walls to place them in position for stapling. The cushioning effect The single I thus provided enables pressure packing of the contents in the container, and not only protects the contents against rough handling of the container when packed, but compensates for shrinkage thereof, and thereby maintains the pressure packed condition until the commodity reaches the consumer. The degree of such cushioning effect can be varied by a judicious selection of the stapling locations, and also by altering the number of staples employed in stapling these tabs.

Certain of the perishable commodities are known to be more sensitive to abrasion and bruising than others, and might conceivably be exposed to injury, if in their packed condition, they were maintained in'pressure engagement against a relatively sharp edge such as might be presented by the edges of the cushioning tabs if untreated. This possibility is avoided in my improved container, by the scalloping of the edges of the tabs as described, since the scalloping of the edges has the very beneficial effect of softening such edges, by destroying the stiffness and sharpness that might otherwise be inherent therein.

Portability of the container is made convenient by a handle formed integrally from the midportlon 35 of the intermediate section 33 of the .blank C. Each pair of curved die cuts II and associated score lines 39 to each side of the longitudinal axis, define one of a pair of handle elements 11 which, when raised to upright position for use, cooperate to form the handle. Each ele-' ment carries with it a tab 19 adapted to be bent along the score line 45, in the direction of the opposing handle element. In use, the handle may be grasped, with the free opposing edges of these talfi in contact, or the tabs 19 may be permitted to overlap, in which latter case, the upper will bear against the opposing handle element and maintain suitable spacing between the two handle elements to give thickness to the handle. At the same time, the lower tab, being of the same size as the upper one, is precluded from protruding beyond its oppositely disposed handle element and presenting a sharp, uncomfortable edge to the hand.

the side wall panel 2|. The blank A to which the blank C is stapled to complete the top wall of the container, is formed with both closing tabs l1 and I1, one along each of the longer sides of the top wall panel I.

In assembling this modified container, the blank C, which is identical to blank C of Figure 1, is stapled to the top wall panel I of the blank A, and the tabs 59 associated with the end wall panels 3| of this blank, are bent around the tabs l5 extending from the ends of the 'top wall panel, and stapled thereto. The side walls are formed by folding in the tabs 83 and 21' associated with the side wall panels 2| and 2|, and then bending the side walls at an angle to the bottom wall. The bottom wall is assembled to the end wall structure formed from the blank C, in the same manner as in the previous embodiment, that is, by inserting the bottom wall tabs underneath the tabs associated with the end walls, and stapling them together. In stapling the closing end of the side wall 8|, the tabs 83, by being cut" short, do not require insertion of the tab ll preliminary to stapling, and offers the additional advantage of eliminating one thickness of material to be stapled.

The same procedure in packing or filling the first embodiment of my improved container, will hold for this modified container. The modified container, however, lends itself somewhat more eillciently to high speed assembling by machin- 7- All other features pointed out in connection with the first embodiment will be found to exist in the modified container just described.

Both embodiments of my improvedcontainer .may be collapsed following stapling of tne components, and caused to lie fiat. The embodiment of Figure 2 will assume a collapsed form as indi- 40 cated in Figure 8, whereas the embodiment of As a slight modification to the container already described, I contemplate scalloping the free edge of the side wall 64', except for a short intermediate portion 80 of such edge to which the removable tape 13 may be applied. The scalloping of this edge, in addition toenhancing the appearance of the container, also serves to identify and distinguish th cover of the container from the opposing side wall.

In Figures 10, 11 and 12, I have disclosed a modified embodiment of my improved container which, in outward appearance, very closely resembles the container of my first embodiment and retains substantially all of the structural elements existing in the other. These are identified by similar reference characters. structurally, this second embodiment difiers from the first, in that the side wall 8| corresponding to the side wall 54 of the first embodiment, is hinged to the bottom wall 69 of the container, and the closing tab I1 is formed as an integral part of the top wall- To accomplish this, the blank B which includes the bottom wall panel, has both side wall panels 2| and 2| integrally formed therewith, each such side wall panel being provided with associated tabs 83 and 21. The tabs 83 difier from the corresponding tabs 21 of Figure 1, in being cut short adjacent the free edge of Figure 11 will take the form illustrated in Figure 12. This is very desirable from the viewpoint of conserving space in the shipping and storage of such containers.

The box components may be de 'vered as blanks to an assembly plant, there to be stapled for use, or flattened for storage purposes, or they may be shipped for stapling by the packer as and when he requires the containers.

While I have referred to the containers as being in general formed of stiif, resilient material, specifically I prefer to manufacture the same of what is commonly referred to in the art as corrugated cardboard. Such corrugated cardboard constitutes a pair of outer sheets spaced by an intermediate layer of corrugated paper to which the outer sheets are adhesively secured. Material of this character, accordingly possesses a grain, such graining running with the corrugations.

In preparing the blanks from which the container of my first embodiment is to be assembled, the blanks A and B are cut with the grain running normal to the scor line H defining the boundary between the rectangular panel and the substantially square panel, and in the blank C, the grain runs parallel to the longitudinal axis thereof. When blanks with these grain characteristics are assembled in the manner described, the container acquires characteristics adding greatly to the features attributed tothe construction thereof. The grain in the side and end walls of the container will run vertically between the top and the bottom walls, and inasmuch as corrugated cardboard will withstand greater prescontainer.

asoncsa sure in the direction of the grain, it follows that the direction of the grain in the side and end walls will be conducive toward withstanding stresses applied to the top wall. This strengthening factor, when added to the bracing effect of the cushioning tabs, results in a container capabio of supporting considerable weight before showing signs of collapse. Added bracing may also be realized by increasing the length of the tabs l5 and associated with the top and bottom walls respectively.

The direction of the grain in the side and end walls has a further beneficial eflect in connection with the scalloping of the free edges of the cushioning tabs, in that such scalloping tends to cut through and destroy the stifiening efiect given to the material by the intermediate corrugations, thereby softening the edge to a much higher degree than would otherwise be possible.

In thetop wall of the container, it will be noted that the grain in the rectangular panel of the blank A is in a direction transvers to the container, whilethe grain in the intermediate sectionof blank C is longitudinally of the This has the strengthening efiect, characteristic of plywood, where the grain of one ply is dir ectedat right angles to the grain of an adjacent ply. The use of a grained material such as corrugated cardboard, in the fabrication of my improved container, thus has the added advantage of enabling one to increase the stiffness and strength of the top wall structure oi the container,

The second embodiment of my invention, as depicted in Figures 10 and 11, mayalso be designed to include grain characteristic similar to those just described.

In lieu of constructing my improved container of the same material throughout, it is within the contemplated scope of my invention to vary the character of such material, as, for example,.

by combining one or more of the blanks of corrugated cardboard with one or more of plain cardboard to enhance the appearance of the finished container or to obtain other desirable results.

It will be apparent from the above description of my invention that it will fulfill all the objects set forth by me. While I have described such container in its preferred embodiments and in great detail, it is capable of further modification and change, without departing from the principles involved, and I do .not desire to be limited in my protection to the specific details set forth, except as may be necessitated by the prior art and the appended claims.
